Each year, the MND Association dedicates the month of June to raising MND awareness. This year, we focus on the eyes – in most people with MND the only part of their body they can still move and the only way left for them to communicate. Alongside the Association-wide campaign, the Research Development team selected six most-enquired about topics, which we will address through six dedicated blogs.
Last year, I wrote about our trip to a brain bank. Here, we learned about how people can arrange to donate their tissue (brain and spinal cord) to tissue banks after they die, and how it is stored and used in MND research all around the UK.
What you might be asking is: what can tissue actually tell us about MND, and how will this help us find new treatments?
To find new drugs that can beat this disease we first need to understand what is going on in the brain, which is very difficult to study in living people. This is why post-mortem tissue from people with MND is an invaluable resource. Below are four reasons why tissue donation is so important. Continue reading →
When diagnosing MND, it is important to look at the activity and impact of the motor neurones themselves – is the electrical message being carried down the nerve properly, and is it reaching the end of the nerve in the muscle? Malfunctions in the electrical activity at the muscle end of the nerve cell result in the muscle twitching that many people with MND experience.
One of the tests used to diagnose MND is an electromyography or EMG test. It involves putting needles into a muscle to measure electrical activity. It can be a painful and unpleasant experience, which doctors and patients are only willing to do when necessary.
There is evidence that ultrasound imaging may be able to detect the same malfunctions in the electrical activity of muscle as EMG, by looking at the way the muscle behaves when electrical activity occurs. Ultrasound images produce the typical grey scale images, for example pictures from baby scans, and can be used to provide images of any muscles in the body. Continue reading →
At present there is no diagnostic test for MND, and diagnosis is usually determined through clinical observations and by excluding other diseases. Because of this, a definitive diagnosis of MND can take up to several months.
By developing an effective diagnostic test for MND, we will be able to diagnose MND earlier and put in place effective care and support needs sooner. Another benefit to earlier diagnosis would mean that people living with MND can be started on riluzole much earlier. Continue reading →
